The option the add a section header or divider line to break up and organize long CMS item forms.
These act purely as visual breaks or instructions for clients to better understand the flow of information input. There would be nothing for the client to adjust with these fields because it's just a label and a line.
Section Header: Similar to a description label for a field but stand-alone and emphasized by font size/weight.
Section Divider: Simply a 1px 100%w line to visual break up the form.
